tunnel type microwave green tea leafs processing machine


Product Description

1. What is microwave ?

Microwave refers to the frequency of electromagnetic wave 0.3GHz~300GHz, is a band limited radio abbreviation. It has penetrate, reflection, absorption of these three characteristics.

For glass, plastic or porcelain, microwave is almost through without being absorbed. And the self heating for water and food will absorb microwave. And on the metal stuff, it will reflect the microwave.

2. Advantage of microwave used in tea leaf drying

(a) Low temeprature heating , nearly no color change,no nutrition lost ,keep good taste of the tea leaves.

(b) Sterilization. Microwave not only can kill most of the bacteria in the leaf , but also can kill the insect .

(c) Cleaning production,no environment pollution,no dust,no noise pollution.

(d) Save cost .Very fast speed ,only need 2-10 mins , heating the tea leaves throughly and uniformly .Compared with the far infrared heating methods,microwave can save 1/3 of the cost.

(e) Big capacity.The machine is tunnel type ,can meet with continuous production.

(f) Easy to operate . The control button is installed in the control cabinet, 1-3 people is enough to control it.

3. The experimental comparison of several different drying methods

1.From this table we can see that different drying methods has a little effect for the color of the leaves.

2.But the microwave is the shortest drying time and lowest energy consumption drying method (This is mainly because microwave can penetrate through the leaves, and the water can evaporate from the surface and internal of the leaves at the same time . )

3.For freeze drying ,the temperature is ten degrees in the drying process, so also can maintain the color of the leaves,but time is longest and energy consumption is largest,not very practical in the industrial production.

1.The effects of different drying methods on metal elements content is not big.

2.But for VC, VE, VA. The microwave drying and infrared drying, for the destruction of the two is the least of them.

3.For the protein and fat,the microwave is the most suitable method.Because now high protein, low fat products are most popular.

4.But time of the infrared drying is longer than microwave drying.And consumption is larger than microwave drying method too.

5.So from these experiments and analysis,we can see the microwave drying machine is the most suitable method for moringa.

4.The machine can be designed according to your requirement.
